This piece of work shows lots of detail although does not fit the typical pop-art theme. It has a dot gradient over his face.
This is a normal pop-art that is found, they have used Jake The Dog from Adventure Time and put colours that contrast with eachother.
Another peice of typically normal pop-art though this is done with someone's lips. The colours work well with eachother as they all contrast.
A modern version of pop-art. Lots of colours used and has a grain, which is common amongst other modern pop-art pieces.

Heinz Tomato Ketchup shows a bright blue background which constrasts with the background. The bottle then has many patterns and colours in it. The image works well as a whole.

Again, this image has lots of colours and patterns. This isnt the most typical type of pop-art.
The pop-art piece is my favourite as it represents two people on the pop art instead of a colour which would be seen on normal pop tart.
